聖奧思定主教（聖師）
聖人在公元354年出生於非洲坦迦，青年時期的生活放浪形骸，但他追求真理之心始終不歿；終因母親莫尼加的祈禱和榜樣，並在聖安博主教的勸導下，回頭歸正。他在387年復活節，在聖安博主教手中受洗。
聖人受洗後，返回非洲故里，度苦修生活，後被選為希波教區主教，以熱情洋溢的講道、論據精辟的著作，竭力維護真理，闡釋信仰，攻斥異端，達35年之久，確是羊群和牧者的榜樣。
聖人430年安逝。聖人著作等身，其中的《懺悔錄》描述了他的皈依歷程；又在《天主之城》一書中，流露他理想的信仰生活；兩書皆為靈修和信仰生活的經典之作。
集禱經
上主，求你在現今的教會，重新振興你昔日賜給聖奧思定主教的精神，全心渴慕你、尋求你——唯一的真理和智慧之泉，聖德和愛情的根源。因你的聖子、我們的主耶穌基督，他和你及聖神，是唯一天主，永生永王。亞孟。
Saint Augustine, Bishop and Doctor of the Church
Born in Tagaste in Africa, St. Augustine (354-430) was raised in the Church but fell into licentiousness and heresy. “My sins increase like a rolling snowball,” he wrote in his Confession. At thirty-three he was baptized by St. Ambrose of Milan, after which he returned to Africa and was later elected Bishop of Hippo. St. Augustine devoted himself to a regimen of preaching and writing in defense of the Faith. One of the most prolific writers ever, he is one of the greatest Doctors of the Church.
Collect
Renew in your Church, we pray, O Lord,
the spirit with which you endowed
your Bishop Saint Augustine
that, filled with the same spirit,
we may thirst for you,
the sole fount of true wisdom,
and seek you, the author of heavenly love.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever. Amen.
